Embodiment 1

[0024] see Figure 1~3 , in an embodiment of the present invention, a clamping structure for steel pipe processing includes a support rod 1 and a mounting plate 2 fixedly connected to the support rod 1; a cavity is provided inside the support rod 1, and the inside of the cavity is from the left To the right, a rotating rod 6, a first adjustment assembly connected to the outer splint 4, and a second adjustment assembly connected to the inner support plate 9 are provided in sequence, wherein the end of the rotation rod 6 away from the first adjustment assembly passes through the mounting plate 2 and is connected with the The rotating handle 3 is fixedly connected. When the rotating rod 6 rotates, the outer splint 4 and the inner brace 9 move toward each other or move oppositely. When the outer splint 4 and the inner brace 9 move toward each other, the inner and outer walls of the steel pipe are fixed at the same time. High, and will not cause damage to the steel pipe due to one-...

Embodiment 2

[0031] see Figure 4-7 , during the specific implementation of the present invention, another embodiment is proposed to realize the separate control of the first adjustment assembly and the second adjustment assembly, specifically, the first two-way threaded rod 8 and the second two-way threaded rod 12 The two connection grooves 14 that rotate mutually are connected by rotation, and the inner side of the connection groove 14 is provided with a locking groove 16, and the locking groove 16 is engaged with the locking block 15, and the locking block 15 is connected with the connecting shaft 13 passing through the first two-way threaded rod 8 Fixedly connected, the other end of the connecting shaft 13 is fixed to the rotating rod 6. Of course, the rotating rod 6 is connected to the first two-way threaded rod 8 in rotation. When in the connecting groove 14, the rotating rod 6 drives the first two-way threaded rod 8 to rotate, and when the block 15 is in the connecting groove 14 fix...

Abstract

The invention relates to the related technical field of workpiece clamping, in particular to a clamping structure for steel pipe machining. The clamping structure comprises a supporting rod and a mounting plate fixedly connected with the supporting rod. The inner side of the supporting rod is provided with a cavity, and the inner side of the cavity is sequentially provided with a rotating rod, a first adjusting assembly connected with an outer clamping plate and a second adjusting assembly connected with an inner supporting plate from left to right. The end, far away from the first adjusting assembly, of the rotating rod penetrates through the mounting plate and is fixedly connected with a rotating handle, and when the rotating rod rotates, the outer clamping plate and the inner supportingplate move close to each other or away from each other. The design is novel; when the arranged rotating rod rotates, the outer clamping plate and the inner supporting plate move close to each other or away from each other; when the outer clamping plate and the inner supporting plate move close to each other, the inner wall and the outer wall of a steel pipe are fixed simultaneously, the firmnessis high, and the steel pipe cannot be damaged due to one-way support; and when the outer clamping plate and the inner supporting plate move away from each other, the steel pipe can be taken and placed, and use is convenient.

Description

technical field [0001] The invention relates to the related technical field of workpiece clamping, in particular to a clamping structure for steel pipe processing. Background technique [0002] Steel with a hollow section whose length is much greater than its diameter or circumference. According to the cross-sectional shape, it is divided into circular, square, rectangular and special-shaped steel pipes; according to the material, it is divided into carbon structural steel pipes, low alloy structural steel pipes, alloy steel pipes and composite steel pipes; Steel pipes for thermal equipment, petrochemical industry, machinery manufacturing, geological drilling, high-pressure equipment, etc.; according to the production process, they are divided into seamless steel pipes and welded steel pipes, among which seamless steel pipes are divided into hot-rolled and cold-rolled (drawn) Two kinds, welded steel pipe is divided into straight seam welded steel pipe and spiral seam welded...
